Jakob Best IVs

Recommended IVs

Stat Superboon/Superbane IV Recommendation
HP (17) HP Superbane ★★☆☆☆
Atk (17) Attack Bane ★★★★☆
Spd (9) Spd Bane ★★★★★
Def (6) Def Boon ★★★☆☆
Res (5) Res Boon ★★☆☆☆

◯ = Stat gains +4 with a superboon, ✕= Stat goes down by -4 with a superbane, - = No assets or flaws

See the IV Checker for All Units Trait Fruits—How to Change IVs

When using an Ascendant Floret, we recommend getting the next superboon if it fits the hero. If not, consider what stat your hero needs most.

+Spd and -HP

Jakob's best IVs are +Spd and -HP. With a boon in Spd, Jakob will have an easier time gaining follow-up attacks on slower foes, and allow him to resist follow-up attacks from most foes. Although an HP bane means -4 to the stat, it is still preferable to making one of his other stats any lower.

+Spd for a +10 Merge

If you are building a +10 merged Jakob, we recommend +Spd. With +Spd and 10 merges, Jakob's Spd will reach 38, making him much more adept at gaining follow-up attacks. However, if you want to increase the overall power of each attack, +Atk is a good option as well.

Effect of Jakob's Refined Weapon

Exclusive Weapon Effect from Refining (Special Effect Type)
JakobJakob's Tray
 SP: 400
Might: 14　Range: 2　HP:
If unit initiates combat, inflicts Atk/Spd/Def/Res-4 on foe during combat.
Effect:【Dagger ７】
【Dagger ７】
After combat, if unit attacked, inflicts Def/Res-7 on target and foes within 2 spaces of target through their next actions.
If unit is within 3 spaces of an ally who has HP < 100%, grants Atk/Spd/Def/Res+4 to unit during combat.
Arena Medal：500　Divine Dew：200

We recommend the Special Effect Refine for Jakob's Tray

If you want to refine Jakob's exclusive weapon Jakob's Tray, we recommend the Special Effect Upgrade. Doing so gives Jakob a +4 buff to all stats when he is within 3 spaces of an ally who has taken damage. This effect is super easy to trigger, and allows Jakob to both cast debuffs and have a stronger role in the attack phase.

Jakob is a ranged physical attacker (range = 2). Therefore, when not accounting for the Weapon Triangle, the amount of damage he deals will be equivalent to his Atk minus the foe's Def stat. Aditionally, he has various skills that can cast penalties on foes and bonuses on his allies.

Jakob Strengths

Exclusive weapon casts debuffs during combat

Jakob's exclusive wepaon Jakob's Tray will inflict -4 to all of an opponents stats during combat. This will help assist Jakob's rather low stats and allow him to inflict damage on the foe, as well as spread debuffs to all nearby foes.

Automatic HP regeneration

Jakob's B Skill Renewal 3 will will let him recover 10 HP at the start of every second turn. Since he can regain lost HP even without a healer on the team, taking a little damage does not stop him completely.

Jakob Weaknesses

Unimpressive stat spread

Jakob's stats are all pretty run-of-the-mill, or even less than average. None of his stats really stand out, and since he does not have triangle advantage on any foes, he can be difficult to really use efficiently. Additionally, he struggles to solo his enemies, so he is best used as a support unit to weaken foes.

Jakob Team and Counters

Teammates for Jakob

Elincia IconElincia Sword Reinhardt IconSword Reinhardt Keaton IconKeaton Altina IconAltina
Cordelia IconCordelia Reinhardt IconReinhardt Cherche IconCherche Legendary Leif IconLegendary Leif

Heroes with Brave Weapons

Jakob's weapon skill will allow him to inflict Def/Res-7 on his foes after combat. An ally with a brave skill can easily rush in to attack the weakened foe for a guaranteed +14 damage and possibly finish them off for good.

Jakob Counters

Lyon IconLyon Sophia IconSophia Sothis IconSothis Robin (M) IconRobin (M)

Units with Raven Tomes

Jakob is a colorless unit, so a foe with a Raven Tome will have Triangle Advantage over him in combat. Nagi will have both Triangle Advantage and distant counter, so definitely do not attack her.

Strong units with Distant Counter

Jakob also struggles against foes that have Distant Counter. If he attacks tanky foes like the Tikis, the chance of him surviving that battle is pretty slim, so even if the intention was just to debuff them, we recommend keeping away.

Jakob as a Source Hero

Jakob Avatar

Value of Skills ★☆☆☆☆

Build Him or Send Him Home!

You can inherit the skill Defense +3 from Jakob, but you can also get it from 4 Star Stahl or Corrin (M), and it really is not that great of a skill to begin with. Renewal 3 cannot even be learned until Jakob reaches 5 stars, so for the most part, he is not all that good for inherit skill. If you do not want to build and use him, we recommend sending him home for feathers.

    Oh. Did you need something? You’ve brought me tea? I’m not thirsty at the moment…
    But I shall drink it nonetheless. I wouldn’t want to waste tea.
    It’s a bit cold. And too bitter. I would never have served it. But... I sense the effort that went into it.
    Regardless of skill, there is flavor in devotion, a taste in affection. You thought of me in making this.
    Next time, I shall make the tea for you, and it will taste better than anything you have ever known.
